Laminar flow used as "liquid etch mask" in wet chemical etching to generate glass microstructures with an improved aspect ratio.
A new method of anisotropic etching an amorphous bulk material is proposed in this paper. Laminar flow is employed in this method to mask the flow of an etchant and is termed as "liquid etch mask". Since this mask has the physical properties of a liquid, it brings several advantages that could not be achieved by any kind of other etch mask in the solid phase. As a consequence, the aspect ratio ...
متن کاملlaminar flow in annular conduits
the flow of fluids in annular conduits has been studied for over sixty years, however the resulted data are very scattered. in this paper the problem is analytically solved, starting out with navier-stokes equations. a computer solution is used to determine the shape of velocity profiles, the discharge and the friction factor in a large number of concentric and eccentric annular conduits. the e...
متن کاملLaminar Flow Analysis in the Channel Bends
In this paper the laminar flow in the rectangular channel bends is simulated using numerical techniques. The turning angle of the channel bend and the area ratio of the channel cross-section are two important parameters to be examined. For flow simulation, the body fitted 3-D continuity and momentum equations are used and a body fitted general purpose code is developed. The existing results of ...

متن کاملOverview of Laminar Flow Control
The history of Laminar Flow Control (LFC) from the 1930s through the 1990s is reviewed and the current status of the technology is assessed. Early studies related to the natural laminar boundary-layer flow physics, manufacturing tolerances for laminar flow, and insect-contamination avoidance are discussed. Although most of this publication is about slot-, porous-, and perforated-suction LFC con...
